South African actor Thembinkosi Mthembu has become one of local television’s most versatile performers, moving between comedy, history, soap, politics and crime with roles that continue to reach new audiences.

From his breakout in Showmax’s Adulting to his portrayal of a Zulu king in Shaka iLembe, Thembinkosi has built a career on characters that demand weight and nuance.

Here are five times he stood out on screen:

1. Bonga in Adulting

Thembinkosi played Bonga in Showmax’s hit drama series Adulting. The show followed a group of friends navigating work, money and relationships in Johannesburg. As Bonga, Mthembu brought warmth and honesty to the group’s anchor.

The role required both comedy and vulnerability, and helped introduce Mthembu to a younger streaming audience. Adulting became one of Showmax’s most-watched local titles.

2. King Dingiswayo in Shaka iLembe

In the historical epic Shaka iLembe, Thembinkosi portrayed King Dingiswayo, the leader who laid the foundation for the Zulu nation. The role required him to perform primarily in isiZulu and carry the political and emotional weight of a monarch.

He played Dingiswayo with quiet authority and strategy, a departure from his contemporary TV roles. The performance was praised for grounding the series’ large-scale story in dignity and restraint.

3. Mabutho in The River

On 1Magic’s The River, he played Mabutho from seasons 3 through 6. Mabutho was ambitious and often caught between family loyalty and power. Over four seasons Mthembu turned the character into one of the soap’s most compelling figures, balancing menace with moments of fragility. The run cemented Mthembu as a strong dramatic actor in South African television.

4. Junior in The Republic

In the Mzansi Magic political drama The Republic, Thembinkosi starred as Junior. The series dealt with corruption and governance, and Mthembu played Junior with restraint. Using minimal dialogue, he conveyed pressure and compromise inside government corridors. The role showed a quieter, more internal side of Mthembu compared to his louder soap and streaming characters.

5. Bandile Biyela in Outlaws

In Outlaws, He starred as Bandile Biyela. The crime drama followed ex-convicts trying to rebuild their lives, and Bandile sat at the center of that tension. Mthembu played him with grit and vulnerability, portraying a man trying to outrun his past while being pulled back in. The performance grounded the series and highlighted Mthembu’s range in action-driven drama.

“It’s been about choosing roles that challenge me,” Thembinkosi has said in previous interviews. “I don’t want to play the same person twice.”

Across Showmax, Mzansi Magic and 1Magic, he has avoided repeating himself. With Adulting and Shaka iLembe streaming internationally on Showmax, and The Republic and Outlaws airing locally, his work continues to reach audiences in South Africa and beyond.

Thembinkosi remains active in television and film, with audiences now watching to see what kind of character he takes on next.
